.Specification forming part of Letters Patent No. 185,833, dated January 2, 1877; application led November 29, 1876.

To clito/wm lit may concern:

Bo it known that T., JAMES OLIVER, of South Bend, in the county ot' St.,Joseph and State of Indiana, have invented certain newV I claimed.

1n the drawing, Figure 1 is a view in side elevation of my plow-colter and its attaching plate and lug. Fig. 2 a top View of the same. Fig. 3 represents modifications ot' the same. Fig. 4 is a view showing the method of attaching the colter and its plate to the plowpoint.

-A is the colter; B a lug, projection, or any equivalent device, proceeding from the lower edge of the colter where it joins the'upper portion of the plow-point, said lug 01' projectionentering and littin g into a corresponding recess made in the port-ion ot' the plow-share or point adjacent below. C is a thin plate or flange attached to the rear edge ot' the separate coltel A, shaped and bent in such a manneras to conform to the interior surfaces ot' lthe standard and mold-boall, so that it may rest between the said standard and moldboard.

`This pin-plate liange is attached to the colte'reither by riveting, or, preferably', by having the colter cast upon said plate or tiange after having previously been properly fashioned. By this process of casting, the colter VA and plate C are substantially one solid piece, and less liable to accident or derangev Ido not limit myself to the exact size of the plate (l, inasmuch as the same may be made 'to extend so as to well till the space between the plow-standard and mold-board, or it may be cut away substantially as shown in Fig. 3 of the drawing, and the rivet-hole c may be y made a. slot opening toward the rear, as shown l 3, so that the colter and its plate C may be slid into position without detaching the mold-board or removing the bolt, it being necessary' oniy to remove the point of the plow in order to insert it.l

It will be obvious that when the colter A is placed in position with its plate G resting between the lnold-board and plo w-standard, when the bolt passing through the hole or s lot c is fastened, the colter will be securely lixed and firmly held in position. The rear and lower edges of the colter A are shaped to tit closely upon the adjacent mold-board point, and its face or outer surface is fashioned sov that in connection with said point and mold-board a continuous smooth and unbroken surface shall be presented that may be ground over and polished as a single piece, and that may presenta corresponding operating surface.

- \Vhat I cla-im is-V-k v 1. The combination, with the detachable mold-board, standard, and point of a plow, of a detachable colter formed with a thin rear dange, which latter is secured .between the standard and mold-board, thereby preserving an unbroken working face 0n the land-side of the plow, substantially as and for the purpose described.

- 2. The combination, with the mold-board, standard, and point ot' a plow, all formed in independent parts, of a detachable colter constructed with` a thin ange extending rearward between :ne mold-board and standard, and provided with one or more open slots for adjustable bolt engagement therewith, substantially as and for the purpose described.

The combination, with the mold-board,

standard, and point of a plow, all formed in independent parts, of the detachable colter, the latter provided with the flange secured between the standard and mold-board, and also constructed with the lower lug projection seating into the mortise formed in the point, substantially as and for the purpose described.

In testimony whereof 1 have signed my name-to this specification in the presence of two subscribing witnesses.

JAMES OLIVER.
